Application

1-Butyl-3-methylimidazolium tetrafluoroborate may be used as an extractant for the removal of dibenzothiophene (DBS) from liquid fuels via extractive desulfurization.

Other Notes

Ionic liquid used in many reactions, e.g. hydrogenations; asymmetric hydrogenations proceed in higher enantioselectivity than in homogeneous phase; Suzuki cross-coupling at ambient temperature
